If you're a Costco member, your local store should have these in automotive aisle:
I picked one up last year, and for $99, it's a heck of a deal. I had never heard of Arcan either, but I've been using it for a year and haven't had any issues with it. Besides, I figure Costco wouldn't sell a bad jack (do they sell any bad products?) since dead customers are a lot less likely to renew their memberships.
To add yet another positive endorsement of Harbor Freight products, I've also had the Pittsburgh 1.5 ton racing jack for 6 years, and it's worked reliably for all that time. (The only reason I bought the 3 ton Arcan is the 1.5 ton doesn't have as much lift, and the Arcan cost lest than the 2-ton Pittsburgh.) My brother's been using his 2 ton Pittsburgh even longer than that, and his works just fine as well.
